Description: What should you pay attention to when buying explosion-proof electric hoist? When buying explosion-proof electric hoist, you should pay attention to the basic parameters of explosion-proof electric hoist and the quality of electric hoist.
What should I pay attention to when buying explosion-proof electric hoist ? When buying explosion-proof electric hoist , we should pay attention to the basic parameters of explosion-proof electric hoist and quality of electric hoist.
First, consider the basic parameters of explosion-proof electric hoist:
1. Lifting height: As a lifting tool, explosion-proof electric hoist has strict requirements on lifting height. Therefore, when purchasing, you must first select the height of the lifting weight according to the height of the work in your actual use site. The conventional lifting heights are 6, 9, 12, 18, 24, and 30 m. Special occasions can be non-standard according to user requirements. design.
2. Hoisting speed: The hoisting speed of general electric hoists is divided into two types: single speed (8m / min) and double speed (8 / 0.8m / min). Generally, single speed electric hoists are usually used without special requirements (ie CD1 type), if your working condition requires accurate positioning during the lifting of heavy objects, a two-speed electric hoist (MD1 type) can be selected. In general, the lifting speed determines your work efficiency. The higher the speed Electric hoist, the more you can improve your efficiency.
3. Motor power: The motors used for different types of electric hoists are generally not the same. You need to choose according to your actual needs.
4. Voltage: There are many kinds of working places for explosion-proof electric hoists, so the electric hoists use different voltages. They are divided into 380V industrial power and 220V ordinary civilian power, and even larger voltages 440V, 60HZ, 380V, 60HZ and a series of non-standard power supplies.
5. Installation method: Explosion-proof electric hoist is divided into electric sports car type (that is, the upper and lower hooks of the electric hoist can be lifted and moved left and right) and fixed type (only lifting heavy objects can be lifted up and down), and fixed type can be divided into The upper fixing (A1) and the lower fixing (A2), the user can choose the electric hoist suitable for your installation method according to your actual situation.
6. The distance from the bottom of the I-beam to the center of the electric hoist hook: When purchasing electric hoists, pay attention to the distance between the upper and lower hooks, because in some specific workshops, there are specific requirements for the hook distance of electric hoists. There are strict requirements on the spacing, you can choose different debugging electric hoist.
Second, the quality of explosion-proof electric hoists: Electric hoists are used as lifting equipment, so we must put safety first, which makes us must strictly consider the quality of electric hoists when choosing explosion-proof electric hoists. Generally, the quality of electric hoists is judged from the following aspects. Before the goods are seen, that is, the procurement stage. Generally, you must ask the origin, material, model of the motor, and the brand of the electric hoist. With price. Whether the explosion-proof coefficient and explosion-proof level can reach the environment of your actual operation;
